Really well done.
The physical aspects are outstanding. The elaticity of the stars' points, bounding around off of walls, and squeezing through spaces. I also like the zooming out while controlling the rotation of the board with several different stars, and the ability to split an already segregated star who is off on his own into more when he alone grows. Makes for some pretty interesting scenarios.
There just seems to be something missing in terms of content. The premise is a bit odd, for one, and the story is really loose and doesn't really draw you in to what is going on. And what is with having to collect treasures, but then shaking them off to make more room? You're forced to collect them... then you're forced to throw them away? Seemed kinda odd. Anyway... excellent design and programming effort on this one, for sure. Just doesn't have the kind of addictive content that would draw me back for more.
